5.22 is what percent of 72.5 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 72.5 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 72.5, so we can write it down as 100%=72.5.
4. We know, that x% equals 5.22 of the output value, so we can write it down as x%=5.22.
5. Now we have two simple equations:
1) 100%=72.5
2) x%=5.22
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=72.5/5.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.22 is what percent of 72.5

100%/x%=72.5/5.22
(100/x)*x=(72.5/5.22)*x       - we multiply both sides of the equation by x
100=13.888888888889*x       - we divide both sides of the equation by (13.888888888889) to get x
100/13.888888888889=x
7.2=x
x=7.2

now we have:
5.22 is 7.2% of 72.5
